Rhythmic gymnast Aliya Protto was the star of the show as she sealed a hat-trick of titles, reigning supreme in the ball, hoop and club disciplines.

The 20-year-old topped the podium in the ball event with a score of 17.033, which saw her finish above team-mate Camilla Feeley and Australia’s Danielle Prince, who earned silver and bronze respectively.

Protto secured the hoop title by recording a total of 17.316, with Feeley again taking silver, while the bronze went to Yili Wang of China.

She was then able to ensure she ended the competition with a third individual crown thanks to another dominant performance as her routine was rewarded with 16.900 points.

American Brigita Budginas was second and Australia’s Prince claimed her second bronze of the day.

After two disappointments, Feeley finally got her hands on gold with a fluent display in the ribbon competition as she scored 17.200 to clinch victory in front of Protto, while Prince added another bronze medal to her individual haul.

The American men were in excellent form across all six artistic apparatus as they swept the gold medals on offer, with Donnell Whittenburg, vault bronze medallist at last year’s World Championships in Glasgow, picking up two titles.

The Pan American Games gold medallist won the rings event by leading home an American one-two on 15.925 as team-mate John Orozco was forced to settle for silver.

Cai Weifeng of China did enough to earn bronze.

Whittenburg then returned to pip Cai in a thrilling parallel bars final as he finished 0.050 ahead of the Chinese competitor on 15.800, with Javier Sandoval of Colombia winning bronze.

Alex Dalton, the 2013 World Championships silver medallist, claimed gold on his preferred apparatus as he secured victory on the floor by recording 15.625, which was enough to oust compatriot Eddie Penev and Aaron Mah of Canada.

Alex Naddour negotiated the tricky pommel horse with ease for a score of 15.650 to beat fellow American Sam Mikulak and Wu Xiaoming, before Penev sealed a surprise success in the vault, edging Whittenburg with a total of 15.100.

Yujiro Terachi of Japan was the recipient of the bronze medal.

Olympic floor champion Aly Raisman of the US gave her hopes of defending her crown at Rio 2016 a boost by taking gold on the apparatus after her routine was given 15.100.

That proved enough to condemn team-mate Brenna Dowell to silver and Shallon Olsen of Canada picked up bronze.

The Canadian gymnast was the one to break the American monopoly on the gold medals as she topped the podium in the vault.

Olsen’s effort was rewarded with 14.750 as she beat Brittany Rogers of Canada and New Zealand’s Courtney McGregor.

American Ashton Locklear’s 15.625 on the uneven bars was too good for the rest of the field, with Larissa Miller of Australia and Rogers taking silver and bronze respectively.

Normal service was resumed on the balance beam as Ragan Smith led home a one-two for the United States by virtue of scoring 15.225 as Raisman sealed silver.

Nagi Kajita was able to finish the event on a positive note as she claimed bronze.

“I’m sure these judges will be judging us at the Olympics so it’s good to have that and hear what they have to say,” Raisman said.

“And just being around all the other competitors puts you in the zone for the Olympics.”
